基于非线性主成分分析法的区域物流发展综合评价模型

Model of the Regional Logistics Developmental Integrated Evaluation Based on Nonlinear PCA

利用非线性主成分分析法对河南各地区的物流发展状况进行分析,将得到的综合主成分指标代替原来较多的评价指标建立模型,对河南各个地区的物流发展综合实力进行评价.结果表明,该方法能够把复杂的问题简化,所得结论科学客观、可信.

In this paper, the nonlinear principal component analysis（PCA） was used to analyze regional logistics development of Henan. The obtained integrated principal component index was used to replace the many indexes to construct model, and then the regional logistics developmental integrated strength was evaluated with the model. The results show that this method can predigest the original complicated problem and come to a scientific objective and reliable conclusion.
